This is an APEXEL smartphone macro lens.
I purchased it in May of this year but mistakenly bought the wrong item, so I am selling it.
It was taken out of the box and attached to my smartphone.
It has been stored in my apartment.

[Industry-First Variable Focal Length Macro Lens] The world's first smartphone macro lens with a variable focal length of 1.5-4.5cm. Unlike traditional fixed-focus lenses, the ZM100 allows you to adjust the magnification based on your distance to the subject (10x at 4.5cm, 20x at 1.5cm).

For further magnification, first move closer to the subject (1.5cm-4.5cm) and then adjust the focus ring at that distance. *Focus will not be achieved if you turn the ring while changing the distance.
